Membrane separation of the base-catalyzed depolymerization of black liquor retentate for low-molecular-mass compound production

One way of valorizing the lignin waste stream from the pulp and paper industries is depolymerizing it into low-molecular-mass compounds (LMMC). However, a common problem in the depolymerization of Kraft lignin is the low yields of small aromatic molecules obtained. In the present work, the combination of the repeated depolymerization of lignin and the separation of LMMC from depolymerized lignin t

Altered Cell-mediated Immunity and Increased Postoperative Infection Rate in Long-term Alcoholic Patients

Background: Preoperative alteration of T cell-mediated immunity as well as an altered immune response to surgical stress were found in long-term alcoholic patients. The aim of this study was to evaluate perioperative T cell-mediated immune parameters as well as cytokine release from whole blood cells after lipopolysaccharide stimulation and its association with postoperative infections. Methods: F

Measurement of the mass and width of the W boson in e+e- collisions at √s = 189 GeV

A measurement of the W mass and width has been performed by the DELPHI Collaboration using the data collected during 1998. The data sample has an integrated luminosity of 155 pb-1 and an average centre-of-mass energy of 188.6 GeV. Results are obtained by applying the method of direct reconstruction of the mass of the W from its decay products in both the W+W- → lvlqq′ and W+W- → qq′qq′ channels. T

Antifilaggrin antibodies in early rheumatoid arthritis may predict radiological progression

Objective: To elucidate the possibility that autoantibodies to filaggrin, detected in patients with early RA (having a disease duration of not more than one year), may predict joint destruction assessed after five years of observation. Methods: This is a 5 yr extension of a previous study (1) of 112 consecutive patients with early RA. Serum antifilaggrin autoantibodies were detected by immunoblott

REVIEW OF ANTI-CORRUPTION LEGISLATION OF THE REPUBLIC OF UZBEKISTAN AND ISSUES OF ITS FURTHER IMPROVEMENT

The article is devoted to an analysis of legal acts of the Republic of Uzbekistan on counteraction against corruption. The article provides the classification and review of the anti-corruption legislation of Uzbekistan. The article also deliberates about the measures taken by Uzbekistan to implement relevant international legal standards into the national legal system. It considers not only the le

Progress in the use of electrospun nanofiber electrodes for solid oxide fuel cells : A review

The application of one-dimensional nanofibers in the fabrication of an electrode greatly improves the performance of solid oxide fuel cells (SOFCs) due to its advantages on electron transfer and mass transport. Various mixed ionic-electronic conducting materials with perovskites and Ruddlesden-Popper-type metal oxide structures are successfully electrospun into nanofibers in recent years mostly in
